Influenced by considerations not only from psychology but also from modern physics, parapsychology, practical divination, esotericism, and the history of philosophy and religion, the theory of synchronicity can be seen as an attempt on Jung’s part to resolve a tension he experienced both in his culture and in his own nature between the domains of personal (religious) meaning and objective (scientific) knowledge.
It is a difficult and controversial theory, the complexities and implications of which have still not been fully worked out.
Recent studies have explored the implications of the theory for psychotherapy, holistic science, parapsychology, and religion.
The theory has also been examined in relation to the personal, social, and intellectual contexts within which Jung developed it.
Not infrequently, synchronicity has been appropriated as a theoretical or experiential component in forms of New Age spirituality.
The continuing widespread interest in synchronicity probably stems, at a theoretical level, from the challenge it purportedly represents to the causal foundations of secular western thought, and, at a practical level, from its being such a commonly occurring form of anomalous and numinous experience.
